Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed ,April 16,1907. Serial No. 368,801.

ject otthe invention being to provide a novel and etlicient casing adaptedto be placed around a post or pole either before or after the same is planted in the ground,

'the Baid protective casing being of sectional construclionrendering its application caky and practical, and

the mid easing; as a whole. when applied to a post, or

thedike being designed to receive a preservative in liquid or=se|ni'-liquid form and distribute the same to any or all parts ol the planted cud ol the po By means of the device hereinafter fully described. the 'lil'e'of a post may be pmlongbd indefinitely, the protu'tive'casing being renewable \vlit-tu-vcr necessary without. removing the lmSi. or pole lrulll the ground.

With'the above and other objects in view the nature of which will more fully appear as the description proceeds, the-invention consists iii the ltuvcl construction, combination and arrangement of parts ln-rcin t'nlly- 'deseribed, illustrated and claimed.

- in the aecompainving drawings: Figurc l is a side elevation of a post or pole with lhc'protectivc casing applied thereto. Fig. 2 is a vertical sect ion through the protector, showing the pmt in elevation. Fig. I! is an enlarged horizontal section through the same. Fig. 4 is a bottom plan view oi the protector, with the bottom or base l't'llttlVr-tl. Fig. :3 is a detail view of a pop lion of modilicd stave.

The protcctiv casing or |nott' 'lor as it ton incalled, is of sectional construction, that i.-t to savit is composed of a suitabilnlunborol' stores I each olar uate form or shape in cross st-t'tion as shown in Figs. 3 and 4, the whole sct ol' SitHth', when combincd and put together. forming a circular or cylindrical casing as shown in said lignrcs. the internal tlilltt-ltslullsul stltll casing being equal to or slightly greater than th cx ternal diann-ter of the post or poltinclosed thereby and shown at 2.

Under the preferred embodiment of this invention all of the staves rest at their bottom ends upon a base or disk-shaped block 3. which base may be secured in place by passing a screw 4 or its equiva-lcnt through the base upward into the bottom of the post. as shown in Fig. 2. The staves are supported by the said base and The inner face of each of the staves l is grooved from to to bottom as shown at 7 and these grooves may extend straight up and down or they may be disposed spirally as may be lotlnd most expedient. the grooves 7 being designed to receive and carry a suitable preservative down around the post and distribute the same to all the snrlaceol the post which lies beneath the surla-ce ot' the ground. At their top edges. the slaves l are beveled inward as shown at 8 to form alt-annular receiving pocket [or the preservath-e with which pocket. all of the grooves 7 comnnmicate. The top edges of the staves are also beveled outwardly as shown at 9 to conform to the [late of a cap 10 ot' conical shape which tit-s around and fastens to the post or pole 2 above the upper ends of the slaves l, as shown in Figs. Land .2. the lower larger end of the cap, which forms anel'leetive water shed. restin upon the beveled upper ends oi the staves. as bestillustmted in Fig. 2. This cap may be made of tin plate, galvanized sheet iroI'i' er canvas made water proof, and the upper edge sets into'ai groove or'annular seat termed in the post 2, while the endsol the cap are overlapped as indicated in Fig. l and beldtog'et her by a suitable fastener 11, which is driven through said over lapping ends into the post. If desired the meeting edges of the staves may be beveled'off adjacent to their inner surfaces to form additional grooves 12 for carrying the preservative around the post;

The pr tective casing'above described need not have a perl'ectly smooth lit around the post but only a firm lit, in order to prevent any ltmseness in the post, and in this way the protector adds materially to the stability ot' the post by increasing the size and circumference of the same.

in practice the stave-s will be put together in the form of a circular or cylindrical casing, in sets of any required length, width and circumference and then immersed in or brushed with coal tar. crude petroleum or like substance to exclude water and keep them from war ing and when dry the slaves may be tied up in bundles ready for use or shipment; or each stave may be separately immersed. if desired an outer covering of galvanized sheet iron or any composite like tarred rooting material may be secured around the outside ol' the stares under the cap and extended downward any depth to aid in resisting the attack of the moisture.

- This outer covering is shown at 13.

are secured together by Ullt' or more bands or h ops 5 encircling all of the slaves. and these hoops may be held securely in place by staples 6 or other suitable fasteners.

The use of the protector above described renders it practicable to use more shapely and expensive or inexpensive posts and poles. as the life of the same is greatly increased. The stares may be made of any wood, prelerably cedar. redwood, chestnut, locust. elm and the more durable hardwtmds The staves may, if desired, be painted inside and out and may be composed of matet'ial other than wood such as portland cetnent or concrete, pottery, vitrified brick material, etc. Additional preservative may be supplied to the inside of the tit) protective casing as often as may he found necessary, the grooves permitting the same to circulate freely around all portions of the post or pole under the cap and prevent decay. To supply such preservative it is only necessary to remove the cap or shed 10.

It is to he understood that the outer covering need not extend clear to the bottom of the casing. also that said casing need not extend entirely to the bottom oi the post or pole, the length of said parts being governed by the depthto which the moisture reaches and other conditions which will suggest the proper lengths. The capillary fissures or grooves on the inner side of the staves will ordinarily extend straight and lengthwise oi the casing as indicated in Fig. 2, but they may extend anguiarly or diagormliy as indicated in Fig. 5. It is also within the scope of this invention to make the stavcs of varying widths to suit and to enable the casing to he made of the proper size in diameter. staves fail to come together at any point any suitable filling may'he inserted to close the gap, and the same covered with galvanized iron or the like.

I claim i. A protector for'the purpose described embodying a series of stares havim: their inner surineemnrooved. and means for sci-tiring said slaves together in cylindri nl form.

2. A protector for the purpose descrihed omlmdying a plurality of stares having liquid-distriimrl'ng conduits. and

Should the means for securing said staves together'ln cylindrical form.

3. A protector for the purpose described embodying a plurality of sta'ves hound'together in cylindrical form and provided in their inner surfaces wlthucspiilary fissures. and n receiving pocket communicating With said fissures. substantially an and for the purpose specified.

4. A protector for the purpose described embodying a plurality of sieves bound together In cylindrical form and having their meeting faces beveled forming grooves for the distribution of a preservative. suhstantislly as described.

A protector for the purpose described embodying a plurality of stoves. n bass upon which said stave's rest, means for-fastening all of the staves together in cylindrlcn'l form. and a water shedding cup fitting over the upper ends of the staven and composed of a strip oi sheet material having the ends thereof overlapped and fa tened to the post.

ti. A protector tor the purpose described, embodying a plurality of slaves. a post or pole provided with Lgroovc around the name above the stnves. and an impervious r oni cap fitting over the upper ends of the stoves with its top edge seated in the groove in the post orpoin. the said cap consisting of a water proof hand wrapped around the post andv upper ends of the staves and having its ends overlapped and fastened together.

in testimony whereof I niiix my signature in presence of two witnesses.
